When you want a way to keep your green fresh as you travel, glass stash jars aren’t too practical. In addition to breaking easily, they’re not exactly stealthy. The perfect alternative? Silicone! You’re used to using silicone for concentrates, but this flexible material is also great for keeping dry herb fresh during travel. These silicone skulls are large enough to hold up to 2 grams of legal dry herb, and the lipped opening creates a strong seal to keep air out.
